cyclen-cored star compounds were functionalized with pyrene moieties on the periphery and used as ligands to produce the corresponding Cu(I) and Cu(II) complexes. The complexation of both ligands was comparatively studied by UV-vis spectroscopy. The Cu(I) and Cu(II) complexes were characterized in chloroform solution by different spectroscopic techniques. These studies suggested that the Cu(I) is coordinated
Two newbipyridineligandscontaining, respectively, two and four pyrene units were prepared. The obtained compounds were employed to synthesize new pyrene labeled ruthenium (II) trisbipyridine complex as well as a pyrene labeled ruthenium (II) trisbipyridine cored dendrimer. The obtained bipyridineligands and the rutheniumcomplexes were characterized by NMR spectroscopy and MALDI-TOF mass spectroscopy
